VALVE.

SPECIICATION forming part 0f Letters Patent N0. 626,420, dated J' une 6, 1899.

Application filed October 10, 1898. Serial No. 693,072. (No model.)

T0 all whom it may concern.-

Be it known that I, GEORGE F. GODLEY, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Valves, of which the following is a specication.

The principal object of my present invention is to provide a durable, neat, and cornparatively inexpensive method of constructing valves and detachable valve-seats.

The invention consists of the improvements hereinafter described and claimed.

The nature, characteristic features, and scope of my invention will be more fully understood from the following description,taken in connection with the accompanying drawings, forming part hereof, and in Which- Figure l is a sectional view, partly in elevation, of a valve embodying features of my invention. Fig. 2 is a similar view illustrating a modified form of my invention. Eig. 3 is asectional view taken on the line 3 3 of Fig. 2; and Eig. et is a perspective View illustrating, on an enlarged scale, the valve-seat shown in Fig. 2.

Referring to the drawings, a is a valve-casing having inlet and outlet openin gs for the reception of supply and discharge pipes and a partition, as a', provided with an opening for the flow of steam or other fluid, such as are provided in the ordinary type of globe-valves. Although this type is shown, myinvention is not limited to same and lis only used by way of illustration. From the partition ct' I extend upward a collar or flange a2, which may be slightly tapered and being of an annular contour in plan. Surrounding this collar or flange a2 very snugly and tightly is a packing-ring b, which is not only held in position by it, but is greatly protected from the steam or other fluids as they pass through the openingin the partition a'. It will be seen in this connection that the steam traveling in an upward direction, as indicated by the arrow in Fig. l, would come in contact with this collar or flange a2, and thus save the packing-ring from being acted upon. Good results have been obtained in practice by making the packing-ring b beveled, which altords a very good bearing-surface for the valve-disk c, which bonnet of the valve-casing.

may also be beveled, when brought to bear upon such ring.

The valve constructed according to my invention consists of the usual valve-spindle, but provided on its lower extremity with an offset, as c', which is adapted for and received by a recessed portion of the disk c and held into position by means of pins or key c2 entering into the wallof the recessed disk, as shown in Fig. 3. This, it will be seen, dispenses with all bolts, nuts, and the like, and not only makes a very effective and quick manner of attachment, but on account of the play afforded makes the valve self-adjusting to any irregularity in the valve-seat that may occur. 4

It is sometimes advisable to use the form of valve-seat in Figs. 2, 3, and 4, Where the packing-ring is held in a detachable valveseat CZ. This valve-seat is best seen in Fig. 4, Where it consists of an annular band provided with a liange CZ', which is adapted to receive and hold iu proper position the packing-ring b. This band is also provided with upwardly-extending arms that engage the In order that these arms may not get into alinement with the discharge-outlet, a lug at e is extending from the valve-casing, and slots d2 are made in the band of the valve-seat d, so that all that is necessary is to drop the valve-seat into the valve-casing thus coming upon and having a bearing on the ring b, and as one or the other of the slots may engage the lug the valveseat is locked and the arms are transverse of the outlet.

It will be obvious to those skilled in the art to which my invention appertains that modifications may be made in detail Without departing from the spirit of my invention, and hence I do not Wish to be understood as limiting myself to the precise construction and arrangement of the parts hereinbefore eX- plained; but,

Having thus explained the nature and 0bjcct of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination in a valve-casing presenting a plane flat seat with an upwardlyextending collar, a packing-ring forced under pressure snugly and tightly around said collar, and upon said seat and securely held thereby from displacement, and free, from eni gagement with any other part of the casing substantially as shown and described.

2. The combination in a valve-casing having a collar, With a detachable valve-seat comprising a band provided with a flange, a packing-ring held in said ange, arms adapted to engage the bonnet of the valve-casing whereby the valve-seat isheld against displacement substantially as shown and described.

3. The combination in a valve-casing having inlet and outlet openings, with a detachable valve-seat comprising a band, arms extending upward from the band, a slot in said band, a lug or plug mounted in the valve-oasing adapted to engage the slot when the Valveseat is dropped into the Valve-casing,where bythe arms are ranged transversely of the inlet and outlet openings, substantially as described.

4. The combination in a Valve-casing having a collar with a detachable valve-seat comprising a band, a packing-ring protected by said band and adapted to surround said collar, the same constituting a bearing-surface for the Valve-disk substantially as shown and described.

5. The combination in a valve-casing having a collar, a packing-ring surrounding said GEORGE F. GODLEY.
